IMPROVEMENT IN AGRICULTURAL STEAMrCOOK ERS.

Specification forming part of Letters Patent No. 191,127, dated May 22,1877; application filed March 29, 1877.

To all whom it may concern Be it known that we, FRANK FARLEY and JOSEPHB. BLACKWOOD, of Keota, in the county of Keokuk, and in the State ofIowa, have invented certain new and useful Improve ments in AgriculturalSteam-Cookers; and do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,making a part of this specification.

The nature of our invention consists in the construction and arrangementof a steam-generator, particularly designed for the use of farmers ingenerating steam for cooking feed, washing, and other purposes, as willbe hereinafter more fully set forth.

In order to enable others skilled in the art to which our inventionappertains to make and use the same, we will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichFigure 1 is a side elevation of our invention. Fig. 2 is a centralvertical section of the same.

A represents a common oil-barrel or other water-tight vessel; and B isan upright sheetmetal cylinder in the center of the barrel A, andextending through the top head 0 thereof.

D is a draft-flue, entering the cylinder or fire-box B at the bottom,and, projecting out through the side of the vessel A, near the bottom,which flue serves as a conductor for the air to the fire on the grate E.

G is the cover of the cylinder B, in which is a pipe-collar, a, for theattachment of suitable pipe to give a brisk circulation to the passingair, causing the fuel to burn freely.

At the outer end of the draft-flue D is a damper, b, for regulating thedraft.

The cylinder-cover G is made of cast-iron, with a hinged door, G, toraise up for putting in the fuel. This cover is not fastened down, butis only held in place by means of a flange, d, fitting inside thecylinder, so that the cover can be removed at pleasure, and with an oldbroom or brush the heating-surface of the cylinder can be easilycleaned, which otherwise would diminish the heat radiated from it. Thefire is easily raked and the ashes removed through the draft-flue D. p

The grate E is a basket-grate, with high sides 0, which protect thecylinder from the burning fuel. This grate can readily be lifted out,when required, by removing the cover G.

The space between the cylinder B and barrel A is to be filled with waterthrough the inlet h in the top head 0 of the barrel; and when the fuelis ignited, and heat is generated sufficient to get up steam, this steamis conducted from a tube, 6, in the top head 0, through flexible tubingI, to a barrel, box, trough, or other receptacle containing the feed tobe cooked. 1

The steam may also be used for cleansing clothes, renovating feathers,or any other purposes desired.

To prevent the solder melting on the top of the barrel, where the plateor collar m is soldered to the cylinder B, a hoop, n, is attached tosaid plate or collar, around and concentric with the cylinder, forming acup, as shown; and when starting steam, or when first starting the fire,this cup is to be filled with cold water, thus making a perfectpreventive removable cover Gr, provided with hinged door G, collar a,and rim d, all substantially as and for the purposes herein set forth.

In testimony that we claim the foregoing we have hereunto set our hands.
